If you haven't seen Moana 2... well, don't watch it. And I say this as a parent who watched Moana and loved it. But if you did watch Moana 2 and thought the plot didn't make any sense, it's because they planned a whole TV show then turned it into a movie at the last minute. This resulted in delightful moments like a villain that comes out of nowhere, and in the course of her intro song has a heel-face turn without any explanation, then disappears out of the movie forever.
